Answer:

$\text{c. }f(n)=3f(n-1);f(1)=2$

Step-by-step explanation:

The first term is 2, so part of the recursive definition is ...

f(1) = 2

The common ratio is 6/2 = 3, so each term is 3 times the previous one. That part of the recursive definition is ...

f(n) = 3·f(n -1)

These two parts of the definition match choice C.

Which represents where f(x) = g(x)?

Alexxx [7]

Answer:

f(2) = 9(2) and f(0) = g(0)

Step-by-step explanation:

As in the expression f(x) = g(x), the values in parentheses need to be the same for both f( ) and g( ). That is only the case for the first answer choice.

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv

Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. $P(Red) = 0.4375$

b. $P(White) = 0.3125$

Step-by-step explanation:

Given

$Red = 7$

$White = 5$

$Yellow = 4$

First, we need to calculate the total

$Total = Red + White + Yellow$

$Total = 7+5+4$

$Total = 16$

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{7}{16}$

$P(Red) = 0.4375$

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

$P(White) = \frac{White}{Total}$

$P(White) = \frac{5}{16}$

$P(White) = 0.3125$
